The aim of this study is to discuss our early results in endoscopic skull base surgery and the development of the learning curve. Patients and Methods: We analyzed our experience regarding 25 patients presented to us in Neurosurgery Department, Assiut University Hospital, Assiut University, Assiut, Egypt in a period of 3 years (2015, 2016, 2017) and operated by endoscopic transnasal approach. All patients signed an informed consent. Results: With the highest percentage was pituitary adenoma 56%, pituitary apoplexy 12%, craniopharyngioma 12%, CSF rhinorrhea 12%, Planum sphenoidal meningioma 4% and suprasellar granuloma 4%. 88% of patients were operated without complications, 8% mortality rate postoperative, 12% complication rate and 76% complete improvement postoperative. Conclusion: Endoscopic skull base surgery is a safe approach to the skull base that needs a good experience, practice and good anatomical knowledge. Teamwork between a Neurosurgeon and ENT surgeon is a must for patient safety.展开更多

The use of an endocranial “gasket” plug has been reported for this and is used in our institution. We present a simple refinement of the “gasket” technique using commonly available materials that helps ensure proper size and positioning of the gasket by applying stress on a suture attached on the center of the gasket implant. Materials and Methods: We report a case of massive CSF leak following endonasal transsphenoidal surgery for pitui- tary macroadenoma. The skull base was reconstructed in a multi-layered fashion with fascia lata and bony buttress reinforced with a vascularized nasoseptal flap. In order to avoid implant slippage from too-small size or malpositioning, we performed a “stress test” using traction applied to a suture attached to the center of the implant (Medpor?), which allowed us to confirm intraoperatively that the buttress was positioned securely. Results: The patient did well without recurrence of CSF leak. At two-year follow-up, there has been no recurrence of CSF leak or occurrence local complica- tions. We have not verified whether bony regrowth into the implant has occurred. Conclusion: The suture-pull refinement of the gasket implant technique is a simple, inexpensive and low risk method to assure secure endocranial positioning over the skull base defect, and may prevent CSF leak resulting from too-small sizing or buttress malpositioning.展开更多

Methods： Soft and hard tissue defects of the anterior skull base were successfully reconstructed in 43 patients during a 1-stage surgery through the use of frontalis muscle galea aponeuretica skull flaps with 1 or 2 vascularized pedicles. The skull flap areas were up approximately 7 cmx 14 cm. Results： Intracranial infection and cerebrospinal fluid leakage were not observed in the 43 patients, and all incisions healed. Of 33 malignant tumor patients, 25 patients received follow-up examinations for longer than 2 years, and 18 patients survived for 2 years. Conclusion： Frontalis muscle galea aponeurotica skull pedicle flaps provided a constant blood supply and re- suited in soft and thin tissue. The pedicle flaps, together with the external cranial bone plate, strengthened the support, but still allowed for bending and shaping. In addition, the flap harvesting approach was consistent with surgery approach, without aesthetic compromises.展开更多

We have developed a detailed concept on training these surgical skills on the lamb's head. This simple and extremely cheap model offers the possibility of training even more demanding and advanced procedures in human endonasal endoscopic surgery such as: frontal sinus surgery, orbital decompression, cerebrospinal fluid-leak repair followed also by the naso-septal flap, etc. Unfortunately, the sphenoid sinus surgery cannot be practiced since quadrupeds do not have this sinus. Still, despite this anatomical limitation, it seems that the lamb's head can be very useful even for the surgeons already practicing EESS, but in a limited edition because of a lack of the experience and dexterity. Only after gaining the essential surgical skills of this demanding field it makes sense to go for the expensive trainings on the human cadaveric model.展开更多
